CLAIM: "Iran not only defies inspectors, it plays a pretty good game of hide and cheat with them. ... Right now, Iran could be hiding facilities that we don't even know about."

BOTTOM LINE: Iran has frustrated inspectors and concealed aspects of its nuclear program over the years, but the country is believed to be in compliance with its commitments now, International Atomic Energy Agency Director General Yukiya Amano told CNN in November.

Amano, though, said he can't yet confirm that Iran's enrichment program is peaceful in nature. He said, "We can verify that they are honoring the commitment that they have made, and we give the assurance every month, but the problem is that we cannot yet give the assurance that all nuclear activities in Iran is in peaceful in purpose. We cannot yet give the clean bill of health."

CLAIM: "Iran's Supreme Leader ... says Iran plans to have 190,000 centrifuges, not 6,000 or even the 19,000 that Iran has today, but 10 times that amount -- 190,000 centrifuges enriching uranium. With this massive capacity, Iran could make the fuel for an entire nuclear arsenal, and this is in a matter of weeks, once it makes that decision."

BOTTOM LINE: Ayatollah Ali Khamenei made that statement in July. Ali Akbar Salehi, the head of the Atomic Energy Organization of Iran, clarified those comments the next day, saying the supreme leader had been addressing the country's long-term needs and not its immediate plans.

CLAIM: Under the deal currently being negotiated, Netanyahu said, "not a single nuclear facility would be demolished ... Iran's breakout time would be very short -- about a year by U.S. assessment, even shorter by Israel's."

BOTTOM LINE: The Institute for Science and International Security in February 2014 estimated that Iran's ability to "break out" -- to produce enough weapons-grade enriched uranium for a bomb using facilities it's already declared -- to stand at about two months. To 'break out' without being caught by the international community, Iran would have to enrich uranium at facilities it hasn't disclosed to the IAEA, and that organization has said it can't be sure that such facilities don't exist. Differences over Iran's breakout time are a key sticking point in the negotiations, with the United States and other world powers pushing for that period to be extended to at least one year by limiting the type and numbers of centrifuges Iran can use and the amount of enriched uranium it can keep.

CLAIM: Equating Iran with ISIS, Netanyahu said that "one calls itself the Islamic Republic. The other calls itself the Islamic State. Both want to impose a militant Islamic empire first on the region and then on the entire world."

BOTTOM LINE: The leaders of the Iranian Revolution ushered in a view of universal rejection of the West, but in recent years it hasn't clearly articulated the late Ayatollah Khomeini's vision for clerical rule beyond Iran itself. For its part, ISIS, or the Islamic State, does not recognize traditional borders and seeks global expansion. For ISIS, recognition of national borders is ideological suicide.

CLAIM: "Backed by Iran, (President Bashar al-) Assad is slaughtering Syrians. Back by Iran, Shiite militias are rampaging through Iraq. Back by Iran, Houthis are seizing control of Yemen, threatening the strategic straits at the mouth of the Red Sea. Along with the Straits of Hormuz, that would give Iran a second choke point on the world's oil supply."

BOTTOM LINE: A United Nations panel reported in 2013 that Turkey had seized assault rifles, explosives, detonators, machine guns and mortar shells that Iran had sent to Syria. U.S. officials have said there is strong evidence that Shiite militias are using Iranian weapons to attack U.S. troops in Iraq. Yemeni officials have frequently accused Iran of providing financial support and weapons to the Houthis in an effort to control Yemen's Red Sea coast, on one of the world's busiest shipping lanes.

"Selma was a great, quiet, quaint place to grow up in," said Thicklin. It's where they learned to love and embrace each other he added.

"I call myself or we call ourselves children of the movement. Children of the civil rights."

Thicklin graduated from high school and Selma and left in 1982. This week, he is making a pilgrimage back home. He plans to take part in the 50th anniversary of the civil rights march from Selma to Montgomery.

Thicklin said it was a voting rights march that brought America's worst nightmare to bear.

March 7, 1965 is known as "Bloody Sunday."

As marchers attempted to cross the Edmund Pettus bridge in Selma, they were confronted and beaten by state troopers and local law enforcement.

"There were many people there who's lives were brought to almost inches of death as a result of this," Thicklin said.

Thicklin said it gained national attention, which brought about Dr. Martin Luther King Jr. calling for people to come down to Selma and finish the march.

The marches led to the passing of the Voting Right Acts of 1965.

Thicklin said our nation has made big strides when it comes to civil rights, but there is still work to be done.

While in Selma, Thicklin said he plans to shoot a documentary of the anniversary, so he can show can educate the younger generation about the historical event.

This pocket of 2,000 men and women constitutes the nation's biggest concentration of homeless people living and sleeping on public sidewalks, in scattered camps under tarps.

Not surprisingly, sanitary conditions are appalling.

This quarter of despair is now at the center of national attention for another reason: This week, Los Angeles police and a homeless man in a tent engaged in a confrontation, ending with officers fatally shooting the man known only as "Africa," an apparent reference to his home continent.

It was all captured on video by bystanders. Police allege "Africa" tried to reach for an officer's gun, prompting the police gunfire against him.

"Skid Row is a 54-block area that has the largest homeless number of individuals in the country," said Jerry Jones, executive director of the National Coalition for the Homeless.

He's based in New York City.

"New York City has the largest homeless population, but Los Angeles has the highest unsheltered population in the country, which has led to the destitution you see today," he added.

New York City's unique right-to-shelter mandate ensures "temporary emergency shelter to every man, woman, and child who is eligible for services, every night," the city's website says.

But not in Los Angeles, where two-thirds of the county's 40,000 homeless people are unsheltered, Jones said.

So many live on the streets of downtown Los Angeles -- and elsewhere.

Land of contrasts

In some American minds, Los Angeles may conjure up images of a great American city cursed with an abandoned urban core.

That's an old memory.

Today, downtown Los Angeles enjoys a renaissance, right down to the new hotels and mall surrounding the Staples Center, where professional basketball and hockey are played, often to championships.

But not on Skid Row. (That's its official designation. Even Google maps label it so.)

There are few champion moments here.

The only exception may be the everyday heroes who labor in 107 charities and agencies feeding and comforting the lost souls bivouacked on the street.

The triple-digit number of social service agencies, however, is often cited as one reason that Los Angeles endures as the nation's Skid Row capital: There's a $54-million-a-year charitable infrastructure anchored to the poverty district.

Nobody seems to be going anywhere.

One man's fall and rise

That doesn't deter Ryan Navales, manager of government and public affairs for the Midnight Mission, which strives to lift people out of poverty.

His work and those of his peers is like that of Sisyphus to the rock, the mythic figure whose endless labor was to push a rock to the top of a mountain and then have to do it all over again after the rock rolled downhill.

"Skid Row has become less transient," Navales said. "The history of skid row goes back to a transient neighborhood associated with the railroad. The true definition of transient is short term. Now it's long term. It's become a neighborhood."

Navales cites a shortage of affordable housing as a reason for how "there's no place for people to go."

He asserts his agencies and others offers hope to those who feel hopeless.

Navales knows from personal experience.

He once worked for Microsoft as a network administrator in the 1990s, but he lost it all, including his family.

Drug addiction obliterated his life.

"After destroying my family, in and out of jail, in and out of treatment, I was living on the streets and doing what people have to do on the streets to support a really gnarly heroin habit," Navales said.

"In August of 2011, I was brought to the Midnight Mission homeless," he added. "I had a backpack on."

He now wears a suit, on Skid Row's front line, trying to relieve and unravel the nation's Gordian knot of poverty.

Israeli leader says potential agreement with Iran is a 'bad deal'

Israeli Prime Minister Benjamin Netanyahu warned Tuesday that a proposed agreement between world powers and Iran was "a bad deal" that would not stop Tehran from getting nuclear weapons -- but would rather pave its way to getting lots of them and leave the Jewish State in grave peril.

The differences between President Barack Obama and Israeli Prime Minister Benjamin Netanyahu were on display Monday when the two offered dramatically divergent takes on a nuclear deal with Iran -- even as Netanyahu struck a conciliatory tone during h...

As Israeli Prime Minister Benjamin Netanyahu prepares to make his case on Iran's nuclear abilities in a controversial speech to Congress on Tuesday, nearly half of Americans believe it was wrong to invite him to deliver it, according to a new poll.

During his upcoming speech to Congress, Israeli Prime Minister Benjamin Netanyahu will lay out the details of what he understands to be the nuclear agreement between world powers and Iran, hoping it will prompt lawmakers to question the administratio...

In a dramatic address to the U.S. Congress at what he said was a "fateful" crossroads of history, Netanyahu openly sided with President Barack Obama's Republican critics and sparked an immediate and furious reaction from the White House, as relations between Washington and Israel spun into their deepest chasm for many years.

"We have been told that no deal is better than a bad deal. Well this is a bad deal. It is a very bad deal. We are better off without it," Netanyahu said, building a case that Iran was not just bent on developing nuclear weapons but was determined to "gobble" up defenseless countries in a wider play for dominance in the Middle East.

"We are being told that the only alternative to this bad deal is war. That is just not true. The alternative to this bad deal is a much better deal," Netanyahu said to deafening cheers in the House of Representatives chamber, while issuing a firm warning that Israel would stand alone if necessary to defend the existence of the Jewish people.

The response from the White House was swift and did not even try to disguise anger at Netanyahu, who has been locked in a public tussle with Obama for almost his entire administration and has stepped up his criticism as talks between world powers and Iran on a deal reach a crucial final stage.

Speaking to reporters shortly after Netanyahu finished his remarks, Obama said there was "nothing new" in Netanyahu's address.

"But on the core issue, which is how do we prevent Iran from obtaining a nuclear weapon, which would make it far more dangerous and would give it scope for even greater action in the region, the prime minister didn't offer any viable alternatives," Obama told reporters before meeting with Defense Secretary Ash Carter.

A senior administration official said in language, extraordinarily strong considering the long alliance between the U.S. and Israel, that the speech contained "literally not one new idea; not one single concrete alternative; all rhetoric, no action."

The official said that despite Netanyahu's tough rhetoric, the alternatives to seeking a deal with Iran were much worse and that military action or more stringent economic sanctions would not set its nuclear program back as far as an agreement that would keep it from taking the final steps towards an atomic arsenal for a decade.

"Without a deal, Iran will certainly advance its program -- installing advanced centrifuges, fueling its plutonium reactor and reducing or eliminating its breakout timeline. That would leave us with the choice of accepting a nuclear-threshold Iran or taking military action," the official said.

"Where is the alternative? Simply demanding that Iran completely capitulate is not a plan, nor would any country support us in that position. The prime minister offered us no concrete action plan."

Netanyahu was not in Washington at the invitation of Obama but was asked to give the speech by Republican House Speaker John Boehner in a move that exposed the U.S.-Israel alliance to treacherous domestic partisan crossfire. The fact that he is facing a tough reelection vote in two weeks also fueled suspicion among administration officials that Netanyahu was using the grand stage of a speech to Congress for a political payoff.

His speech trapped many Democrats between their long-term staunch support from Israel and their own president, and appeared to be a painful experience.

"I was near tears throughout the prime minister's speech -- saddened by the insult to the intelligence of the United States as part of the P5 +1 nations," said Nancy Pelosi, the leader of Democrats in the House, referring to the group of world powers negotiation with Tehran, "and saddened by the condescension toward our knowledge of the threat posed by Iran and our broader commitment to preventing nuclear proliferation."

Veteran Democratic Sen. Dianne Feinstein of California described Netanyahu's speech as "powerful" but said he had failed to lay out a solution that Israel would find "agreeable." But Feinstein also signaled disquiet with the administration's plan for a deal with Iran to last 10 years, saying that 15 or 20 years would be a better timeframe.

"One of the things that I've seen in my lifetime is time goes by very fast, and 10 years is not a very long time," said Feinstein.

In a speech punctuated by multiple standing ovations but boycotted by over 50 Democratic lawmakers, Netanyahu warned that the proposed agreement would allow Iran's breakout time -- the period that it would take to race to a nuclear weapon -- to be much shorter than the one year that the U.S. administration is aiming for. Following fierce warnings by U.S. officials, however, he appeared to stop short of unveiling intricate details of the talks between world powers and Iran which Washington says could dash hopes of an agreement.

A fateful historical crossroads

"Ladies and gentleman, history has placed us at a fateful crossroads. We must now chose between two paths," Netanyahu said, calling on nuclear negotiators to call Iran's path and hold out for an agreement that did not leave Tehran with "a vast nuclear infrastructure" and "no easy path to the bomb."

Netanyahu also warned that Tehran was embarked on a long covert terror war against the United States and Israel as well as playing "hide and cheat" to conceal the true extent of its nuclear program.

"The greatest danger facing our world is the marriage of militant Islam with nuclear weapons," Netanyahu said.

"That is exactly what could happen if the deal being negotiated is accepted by Iran. That deal would not prevent Iran developing nuclear weapons. It would all but guarantee that Iran gets those weapons, lots of them."

He added that Iranian proxies like Hezbollah were "clutching Israel with three tentacles of terror," and that Tehran was "charging into the void" and "gobbling up" nations splintered by turmoil in the Middle East as Iran's Supreme Leader Ayatollah Ali Khamenei spewed the "oldest hatred with the newest technology. He tweets that Israel must be annihilated."

He also said the United States should not be fooled because it had a common interest with Iran in seeing the demise of ISIS: "The enemy of your enemy is your enemy," and he warned that the Islamic Republic had a long history of attacking the United States and Israel through a global anti-terror network.

The prime minister began his address by saying that he deeply regretted that his speech was being seen as a political ploy, after walking into the House chamber to a hero's welcome as lawmakers stood and cheered. He said he would "always be grateful" to President Barack Obama for his support of Israel, including much that will never be known for national security reasons.

U.S. officials warn Netanyahu on sensitive details

Top U.S. officials ahead of the speech sternly warned Netanyahu not to reveal secret details of the talks, which are entering a crucial final stage, warning such revelations could have a disastrous impact on hopes for a deal.

"I am confident we have an inclusive and comprehensive picture of what is going on," Intelligence minister Yuval Steinitz told CNN, though he declined to elaborate on the source of the information other than to say it was not from American or "other sources."

Netanyahu's implicit argument was that the size of the enrichment program that Iran could be allowed to keep under the deal, reportedly around 6,000 centrifuges, and its demand to retain a research and development program on more advanced nuclear technology could reduce the time that it would take to race towards a bomb to less than a year if it decided to make one. The Obama administration says its goal is to freeze Iran's program to ensure that breakout time is a year or more to ensure the world has time to act should Tehran cheat on an agreement.

Israeli officials also warned that a research and development program that Iran is demanding the right to keep could help it enrich uranium, the key ingredient for a nuclear bomb, and allow it to break out in as little as six months.

Sources close to the negotiations in Geneva, however, told CNN's Jim Sciutto that the provision regarding more than 6,000 centrifuges is just one of the options on the table of the deal. The sources also said the advanced research program being contemplated would not allow Tehran to build advanced centrifuges that would help it shorten the breakout time.

A betrayal of trust?

White House spokesman Josh Earnest warned on Monday that any revelations using sensitive information would be "betray the trust between our allies."

"That would be true even if the -- these sources were to claim that they had obtained the information from somewhere else," Earnest said.

The speech, which was organized by House Republican Speaker John Boehner without the White House's prior knowledge, has already fueled a bitter domestic political row, as talks between Iran and world powers approach an end of March deadline for a framework agreement.

Obama wasn't expected to watch Netanyahu's address. Instead, he'll be meeting with several of his European counterparts via video conference to discuss the situation in Ukraine, the White House announced Tuesday.

Blunt words from Obama

Obama bluntly said Monday that Netanyahu had been proven wrong about his diplomatic initiative before, telling Reuters that Netanyahu has in the past made "all sorts of claims" about the deal and that "none of that has come true."

Iranian Foreign Minister Javad Zarif told CNN Tuesday that Netanyahu was trying to disrupt talks which he is currently having with Secretary of State John Kerry in Switzerland. "I don't think trying to create tension and conflict helps anybody," Zarif said.

Netanyahu's aides say that Tuesday's speech represented the last chance for Israel to register its dismay at the proposed deal, ahead of a late March deadline for a political framework to be reached between the parties, so it is vital that he explains to lawmakers what is in the draft. But senior Israeli officials also said that senior Democrats asked Netanyahu not to use any rhetoric that would embarrass the president. More than 50 Democratic lawmakers are boycotting the Netanyahu speech.

'A bad deal is worse than no deal'

National Security Adviser Susan Rice told the America Israel Public Affairs Committee annual meeting on Monday that the administration would never sign an agreement that did not guarantee Israel's security.

"I want to be very clear. A bad deal is worse than no deal. If that is the choice, there will be no deal."

Rice also said that Israel's insistence that Iran must stop all enrichment of uranium was unrealistic and took a clear shot at Netanyahu on the eve of his speech.

The appearance on Capitol Hill amounts to a highly unusual case of a foreign leader, who has a fraught relationship with Obama, effectively deciding to side with Republicans in an effort to derail a potentially historic initiative that is one of the president's top remaining priorities.

"The purpose of my address to Congress," Netanyahu told the AIPAC on Monday "is to speak up about a potential deal with Iran that could threaten the survival of Israel."

"I plan to speak about an Iranian regime that is threatening to destroy Israel, that's devouring country after country in the Middle East, that's exporting terror throughout the world and that is developing, as we speak, the capacity to make nuclear weapons, lots of them," Netanyahu said.

The Obama administration says that a deal could verifiably freeze Iran's nuclear program for at least a decade and stop it short enough of developing a weapon for the world to have time to act if it cheats on the agreement.

A deal that falls short?

Netanyahu however, argues that only an agreement that completely dismantles Iran's entire nuclear infrastructure and materials is acceptable, and believes the one on the table falls far short of that demand.

Earnest also said that Obama had not watched Netanyahu's speech to AIPAC and that he doubted the president would tune in on Tuesday when he goes to Congress. In a pointed show of administration pique over the address, Vice President Joe Biden, who normally would attend, is in Guatemala.

Despite the warnings from the State Department and harsh words from the president, the White House did try to tamp down the flaring tensions in addresses by Rice and U.S. Ambassador to the U.N. Samantha Power to AIPAC Monday and in delivering several administration statements of support for the U.S.-Israel relationship.

Still, the President will not be meeting with Netanyahu as is customary, or even speak to him by phone. U.S. officials say that is because a meeting between Netanyahu and the President could be construed as an attempt by Washington to interfere in Israel's general election on March 17.
